I am looking for a way to increase the boiling temperature of my water, without adding off-flavors. Specifically, I want to increase the boiling temperature of my water for cooking pasta. Any ideas what one might be able to use? Any suggestions would be greatly appreciated.

I'm sorry, I should have specified... I'm trying to increase the boiling point while still using the conventional stovetop method for cooking pasta. I'm wondering specifically if there are any substances that are safe for consumption that will increase the boiling point without adding off flavors.
